I NEED THIS FAST! I WILL PUT BRAINIEST IF IT IS CORRECT A group of workers is harvesting berries at a constant rate. An equation

that represents the number of baskets of berries the workers picked over a period of time, in hours, is y = 5x + 10. (a) What are the slope and the y-intercept for the equation that represents the number of baskets of berries the workers picked over a period of time? (b) What are the rate of change and the initial amount? Explain the meaning of the rate of change and the initial amount for the situation. (c) Use graph paper to draw a graph representing the situation. Label the axes appropriately.

A) the slope of the equation is 5, the y intercept is 10. 
b) the rate of change is just the slope, so 5 but it means that they are picking 5 berries over that period of time. the initial amount is just the y intercept which is 10. this is just how many berries you start with.
c)

Wewaii [24]

Answer:

a) 4.387

b) Yes, because np & npq are greater than 10.

c) = 0.017          

Step-by-step explanation:

Give data:

p = 0.69

n = 90

a) a

E(X) = np = 62.1

SD(X) = \sqrt{(np(1-p))}

          =\sqrt{90\times 0.69(1- 0.69)}

          = 4.387

b)

np = 62.1  

q = 1 - p  = 1 - 0.69 = 0.31

npq = 19.251

Yes, because np & npq are greater than 10.

c.

P(X \geq 72   ) = P(X > 71.5) [continuity correction]

=    P(Z> \frac{((71.5-62.1)}{ 4.387})

= P(Z> 2.14 )      

= 1 - P(Z<2.14)              

= 1 - 0.983   (using table)          

= 0.017

Find the slope 3x+5y=29
tester [92]

Answer: -\frac{3}{5}

<u>Step-by-step explanation:</u>

If you solve for y, then it will be in y = mx + b format where m is the slope.

3x + 5y = 29

<u>-3x        </u>  <u> -3x </u>

       5y = -3x + 29

       \frac{5y}{5} = \frac{-3x}{5} + \frac{29}{5}

       y = \frac{-3}{5}x + \frac{29}{5}

m = -\frac{3}{5}

Help asap plssssssss
kiruha [24]

Answer:

127

Step-by-step explanation:

m<PQR and m<RQS are supplementary angles so their sum is 180

3x - 5 + x + 1 = 180 add like terms

4x - 4 = 180 subtract 4 from both sides

4x = 176 divide both sides by 4

x = 44

m<PQR is 3x - 5 replace x with 44

3*44 - 5 = 127
